It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-50168 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-50168/ (Markdown: https://insights.sbomify.com/CVE-2022-50168/index.md)","id":"CVE-2022-50168","markdown":"https://insights.sbomify.com/CVE-2022-50168/index.md","name":"CVE-2022-50168","record":{"aliases":["DEBIAN-CVE-2022-50168","GHSA-mr6m-6rcr-27v3","UBUNTU-CVE-2022-50168"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's BPF JIT compiler allows local attackers to potentially execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, x86: fix freeing of not-finalized bpf_prog_pack\n\nsyzbot reported a few issues with bpf_prog_pack [1], [2]. This only happens\nwith multiple subprogs. In jit_subprogs(), we first call bpf_int_jit_compile()\non each sub program. And then, we call it on each sub program again. jit_data\nis not freed in the first call of bpf_int_jit_compile(). Similarly we don't\ncall bpf_jit_binary_pack_finalize() in the first call of bpf_int_jit_compile().\n\nIf bpf_int_jit_compile() failed for one sub program, we will call\nbpf_jit_binary_pack_finalize() for this sub program. However, we don't have a\nchance to call it for other sub programs. Then we will hit \"goto out_free\" in\njit_subprogs(), and call bpf_jit_free on some subprograms that haven't got\nbpf_jit_binary_pack_finalize() yet.\n\nAt this point, bpf_jit_binary_pack_free() is called and the whole 2MB page is\nfreed erroneously.\n\nFix this with a custom bpf_jit_free() for x86_64, which calls\nbpf_jit_binary_pack_finalize() if necessary. Also, with custom\nbpf_jit_free(), bpf_prog_aux-\u003euse_bpf_prog_pack is not needed any more,\nremove it.\n\n[1] https://syzkaller.appspot.com/bug?extid=2f649ec6d2eea1495a8f\n[2] https://syzkaller.appspot.com/bug?extid=87f65c75f4a72db05445","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"bpf, x86: fix freeing of not-finalized bpf_prog_pack","id":"CVE-2022-50168","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2022"},"n_packages":0,"n_references":3,"next":{"headline":"wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()","id":"CVE-2022-50169"},"packages":[],"prev":{"headline":"bpf: fix potential 32-bit overflow when accessing ARRAY map element","id":"CVE-2022-50167"},"products":["Linux"],"published":"2025-06-18","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's BPF JIT compiler allows local attackers to potentially execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2022-50168/"}
